How to lead a running boar.

[jthyttin]

I'd be really interested to know just what the difference in POI is, between a bullet travelling at circa 2500fps, and another at circa 3000fps, at say 30m, at say 20 kph ? Anyone out there good at maths

Not taking bullet deceleration into account, the difference in flight time is 0.007 seconds. If target is moving 20km/h (5.6m/s) it will amount to 1.5" / 3.6cm.

Lead is a very personal thing. People lead differently (steady vs. accelerate etc.) and act differently pulling the trigger. Most people would be better of not shooting if they have to lead "outside of the fur" and this would restrict the shots to 25 or 50 meters, depending...

Just had a go at trying to work out the difference between POI v bullet speed. I used data from my ballistic calculator, based on a couple of home loads I'd put across the chronograph.


30kph = 8.3mps. Assuming the gun was in a fixed position, I come up with the following, but I'm happy to be corrected.


9.3x62 255gn @ 2400fps: POI = .04 second @ 30yds. Target would travel 33cm

300wm 200gn @ 2880fps: POI =.03 second @ 30yds. Target would travel 25cm


So 8cm difference.


I was surprised it's that much, and I think 30kph is on the higher side. Personally, I don't think it matters what you shoot, just that you're practised with whatever it is.

If you have a play with the Swarovski ‘Lead Distance’ app you can dial in different mv and bc figures. Just tried it with your base figures and @ 14kph it’s a 3cm difference, so doubling the speed might well be around 8cm.

EDIT: In demo mode I’ve run through a range of boar speeds and it produces the following differentials between your 9.3x62 & 300 Win Mag examples:

25kph - 6cm
30kph - 7cm
50kph - 11cm

Thanks. Either way, less of a difference, than I can consistently shoot a running target !

But good to know for those 200m+ shots.

Orion, I did play with the calculator that you linked to. It seems pretty much in line with what other have said about holding on the eye or snout. I'm having a lot of fun with the calculator, I show my kids the running boar and then ask how far to lead, then I show them the calculation. My 10 year old is getting pretty good as guessing the correct lead.
Cheers

If they’re getting to grips with the 2D graphics of the Swarovski app then have a go at the Aimpoint ‘The Driven Hunt’ online game, or download the app to a tablet or smartphone.

It gets a bit hectic round about level 12, so not totally realistic (unless you’ve experienced the ‘Hellfire Corner’ drive in Hungary that Lateral and I enjoyed last year)!



BTW two of my grandsons are starting to show me up on it!

Have a look at wild boar fever on you tube

start at the arse into a arch , sweeze trigger when past the nose . works for me

My running boar experience is very limited. I have shot at only 4.

I killed 3 with the first shot, and the other took 2 shots before it stopped running. Ranges were between 60m and 110m. I remain unashamedly pleased with myself, and offer what follows in that spirit.

The method I followed is what has pithily been described here as "nuts to neck", i.e. pick up the animal at its hind legs, run the dot/crosshairs along its belly then accelerate diagonally up from behind the forelegs and through its head, squeezing the trigger as you do so. This keeps the rifle steady and adjusts its speed to the pace and angle of the animal. It also saves you having to "think" about lead.

All I can say is that it worked for me on the sole occasion I have hunted driven boar. It also enabled me to take a fox on the same day, and another fox would have met its maker too had a sapling not intervened.

I read it the other way, slow, heavy bullets !

Clearly, if the gun is swung too slowly, or the shooter stops swinging as they take the shot, regardless of calibre, the shot will be too far back.

I normally use a 9.3x62, & 9.3x74, but for various reasons, used a 300wm on a trip a month ago. It took me a little time to adapt, because I was missing in front, although that may also have been to do with shooting a 27" barrel with brake, rather than my normal circa 20" barrel, and feeling like I really needed to push through ? But that was soon sorted, and I enjoyed using it.

Do you mean heavy bullet, slow calibres ? Or just people who swing their gun slowly ?

Most of the time red end shots are from the guns moving too slow, the shooter thinking that a mid body shot will do the job. And thinking that, the majority end up further back on the body. The speed of the bullets has not made that much difference, 150grn to 300grn as mention a few posts ago the difference at 50yds is not worth worrying about. I've usually got the dot on the Boars front head, eye area before I shoot. That would cover quartering towards and away and straight on to the gun.
Unless it was like the one some years back in Croatia when I just froze on the Kieler, it was huge I didnt shoot I was froze on the spot.

Swing through like its a low flying phaesant or a fast running rabbit and squeeze as the dot gets just to the snout. Keep about 1/3rd up and no more - there is a lot of hump on a boar - heart and lungs are low down.

And keep shooting. Big and even little Boar can cause a lot of damage to dogs and beaters if wounded. If in doubt put another shot in the head.

When you get to your stand have a really good look and think about where the shots are likely to be. Often Boar will run through trees and brush, but there will be gaps where you can get a clear shot.

But you wont have much time - again don't think rifle, think snap shooting rabbits with a shotgun. If a group comes through - leave the big ones at the front - they will be the old Matriarchs - shoot the smaller and mid sized ones.

If its big and on its own - that will be a big Male - shoot it. But it might have a trophy fee - check before the drive. But if its a a big Keiler, you won't often get the chance to shoot one so just suck up the trophy fee if there is one.

And here is the couple I have shot - top one was a 70 yard running shot across a Rape field - using the Combine as the beater. It was leading out two piglets. German friend double tapped the two piglets. Then a fox ran out and head shot that as it was running. The big sow took off and I just shot instinctively. It bowled like a rabbit with an H Mantle going just under the spine.

The big boar - 100 kg's was shot at 3am. Was sitting in high seat. It was dumping snow so closed the windows and went to sleep. Woke too hear something snuffling and snorting. Carefully opened the window. Big dark lump in the field that was moving - took a few seconds to compute. Cross hair on shoulder - the biggest scream of anger and it charged off into the wood. When it got light and host came to pick me up we went to have a look for it. Slightly nerve racking as I knew the size of it. It had gone 20 yards into the wood - perhaps 50 in total and was dead with a 173gn H Mantle bullet through its vitals.

I Hold on the nose if running well, like you say, depends on your estimate of speed & range.

Nah in the arse !
ha ha like the time in Wasgau

My Berufjaeger pal in Germany had his leg slit open once by a keiler. It was not being aggressive, just was trying to get away from the ruckus of a driven hunt and as they have very bad eyesight it simply ran through him.

Certainly agree with the limited vision bit, two years back I had a cracking Keiler heading straight toward me, unfortunately from a marked up no shoot danger zone, I waited a second to try for a vertical down shot as he passed my two foot high stand, either intentionally or by poor eyesight, he barged the stand leg nearest him as he went through, (Literally!) Rocking my stand enough to put me off balance as I fired, the round must have passed his ear into the deck .... In the heat of the moment I tried for the back of his head as he maintained his course straight as a die, unfortunately the round buried itself in the left ham, the hunter down in the next stand nailed him.

Perhaps if I shot more on the runners at Diggle a bit more, I would improve!

So, let's call it 33yds and pretend the bullet doesn't slow down at all over that distance (it does, of course; and I'd guess the bigger bullets would lose proportionately less speed than the lighter ones?)
2500fps is 833.3yd/s covers 33yds in 40ms
3000fps is 1000yd/s covers 33yds in 33ms
20kmh is about 5.6m/s - so in 7ms the boar has run an extra 40mm.

That suggests (if my arithmetic is correct) that the failure to swing through is more likely to result in gut and haunch shots than 'slow' bullets?

 

[JTO]

Lots of theories on moving targets.
Sustained lead.
Swing through.
Shoot as soon as the gun hits your shoulder.

“If its big and on its own - that will be a big Male - shoot it. But it might have a trophy fee - check before the drive. But if its a a big Keiler, you won't often get the chance to shoot one so just suck up the trophy fee if there is one.”

I wish! I had just this scenario in France last year, with a very large boar creeping out of the wood to cross the allee. I applied the “big lone boar = male” rule, fired, and 70kg rolled over, to reveal a lone sow. If she was alone, then not obviously a matriarch, but I was chastised for the shot nonetheless. Absolutely no regrets, though.

And all the advice about shooting like a shotgun on pheasants is spot on: I use a Chapuis side by side that has the dimensions of a rather svelte 20-bore. With the 9.3x74R barrels, it is distinctly heavier. But it still handles like a shotgun and, with all our shots at no more than c.100m, due to the layout of the forest and allees, open sights are perfect.
